| 英文摘要 | Solar-driven CO2 conversion is an attractive option for producing usable fuels and chemicals. However, traditionally synthesized TiO2 materials suffer from the low activity of CO2 conversion into multi-carbon products. In this study, for the first time, strong magnetic fields were introduced into the synthesis of TiO2. By regulating the splitting ratio of high-angle and low-angle quantum orbitals, we developed a new type of TiO2{100} facets containing more active low-coordinate Ti atoms. In-situ Fourier transform infrared spectroscopy (FTIR) and DFT calculations both revealed that the interfacial charge redistribution and lattice structure of such TiO2{100} are beneficial to the coupling of adsorbed CO*. This enables highly efficient conversion of CO2 into C2H5OH with a yield rate of 6.16 mmol g(-1) h(-1), which is 22-fold higher than that of pristine TiO2. This strategy provides a new platform for desirable photocatalyst synthesis and furthers our understanding of the relationship between atomic orbital control and CO2 conversion. |
